Source description

Kitten TTS mini 0.8 — RLX bundle

RLX compile bundle for KittenML/kitten-tts-mini-0.8. Replaces ONNX Runtime at inference time: rlx-kittentts loads graph.json + weights.safetensors, lowers to RLX HIR, and compiles with rlx-runtime.

Upstream weights (required): download KittenML/kitten-tts-mini-0.8 for config.json and voices.npz.

Files

File	Description
`graph.json`	RLX graph IR (3006 nodes)
`weights.safetensors`	Decomposed model weights (~350 MB)
`manifest.json`	Export metadata (op histogram, I/O shapes)

Quick start

# From rlx-models root
just fetch-kittentts
just fetch-kitten-rlx-bundle
just kittentts -- --native --ipa "həˈloʊ" --voice Jasper --out-wav out.wav

Manual download:

# 1. Upstream ONNX checkpoint + voices
hf download KittenML/kitten-tts-mini-0.8 --local-dir .cache/kittentts-mini-0.8

# 2. This RLX bundle (into rlx_bundle/ subdirectory)
hf download eugenehp/kitten-tts-mini-0.8-rlx --local-dir .cache/kittentts-mini-0.8/rlx_bundle

# 3. Sentinel file for native auto-detection
ln -sf rlx_bundle/weights.safetensors .cache/kittentts-mini-0.8/model.safetensors

# 4. Synthesize (from rlx-models checkout)
cargo run -p rlx-kittentts --features native --release -- \
  --model-dir .cache/kittentts-mini-0.8 \
  --native --ipa "həˈloʊ" --voice Jasper --out-wav out.wav

Layout after merge

.cache/kittentts-mini-0.8/
  config.json              # from KittenML
  voices.npz               # from KittenML
  kitten_tts_mini_v0_8.onnx
  model.safetensors        # symlink → rlx_bundle/weights.safetensors
  rlx_bundle/              # this repo
    graph.json
    manifest.json
    weights.safetensors

Alternatively, set RLX_ONNX_BUNDLE to the bundle directory path.

Environment variables

Variable	Purpose
`RLX_KITTENTTS_DIR`	Model directory (default: `.cache/kittentts-mini-0.8`)
`RLX_ONNX_BUNDLE`	Bundle directory if not co-located with weights
`KITTEN_RLX_WEIGHTS`	Directory containing `model.safetensors`
`KITTEN_RLX_BUNDLE`	Legacy alias for `RLX_ONNX_BUNDLE`
`KITTEN_RLX_HF_REPO`	Override RLX bundle HF repo (default: `eugenehp/kitten-tts-mini-0.8-rlx`)

Re-export

From MIT-RLX/rlx-models:

just fetch-kittentts
just export-kitten-rlx-bundle

Requires: pip install onnx onnxshape numpy safetensors

Crates

Crate	Role
`kitten_tts_mini_rlx`	Bundle → HIR → compile
`rlx-kittentts`	CLI + library (`--features native`)

Inputs / outputs

Tensor	Shape	dtype
`input_ids`	`[1, sequence_length]`	i64
`style`	`[1, 256]`	f32
`speed`	`[1]`	f32
`waveform`	`[num_samples]`	f32 (output)
`duration`	dynamic	i64 (output)
